Fractional lasers are effective and safe for treating acne scars on darker-hued ethnic skin, a new study has found.
Researchers also found that the scar treatments had a high patient-satisfaction rate.
This study may lead to more patients with acne scars opting for fractional laser treatments. Fractional lasers have become increasingly popular in recent years for their ability to minimize the appearance of acne scars. They work by treating the damaged skin in tiny microscopic columns while leaving the healthy skin between those columns untouched. One of the benefits of this approach is a faster recovery time.
The new study, which was conducted by researchers at King Saud University in Riyadh, Saudi Arabia, involved 82 acne patients with darker-hued ethnic skin. Forty-five of the patients were treated with a nonablative fractional laser, and the other 37 were treated with a more aggressive ablative fractional laser.
The patients were followed for 12 weeks. Both groups experienced about the same amount of improvement in the appearance of their scars (just under 40 percent). Overall patient satisfaction was also similar: 71 percent in the nonablative group and 65 percent in the ablative one.
Both types of lasers “are effective and safe for treatment of acne scars in individuals with dark skin complexion,” the authors concluded.
The study was published in the September issue of the journal Lasers in Surgery and Medicine.
